SEWING-IVIACHINE FOR TUCKING.

SPECIFICATION forming part of Letters Patent No. 664,975, dated January1, 1901..

Application flied March 5.1900.- serrano. 7,394. (Nomerie.)

To @ZZ whom t may concern:

Beit known that I, JOHN BUoKLEY SEEL, a subject of the Queen of GreatBritain and Ireland, and a resident of 59 Chapel street, Great Ancoatsstreet, Manchester, county of Lancaster, England, have invented certainnew andusefullmprovementsin Sewing-Machines for Tucking, (for which Ihave filed application for British patent, No. 2,953, dated February 14,1900 5) and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which itappertains to make and use the same.

This invention relates to the combination, with a sewing-machine, ofmeans for forming tucks in or on textile fabrics.

Figure 1 is a side elevation. Fig. 2 is a plan. Fig. 3 is across-section on was of Fig. 2. Fig. 4 is a plan to illustrate theformation of the fold. Fig. 5 is a front elevation showing the action ofthe gage or guider.

An ordinary sewing-machine A (indicated by dotted lines in Fig. 1) isused, preferably in an inverted form, and secured to one of the uprightsof the stand B by a screw ct. The needle and presser-foot are thenunderneath, while the looper b is at the top. A cover-plate as is heldto the needle-plate a2 by screws a6, passing through spiral springs incompression between the cover-plate @Sand the needle-plate a2, so thatby turning the screws the distance of the cover-plate from theneedle-plate a2 may be varied to suit fabrics of different degrees ofthickness.

The cloth in which the tuck is to be formed 1 is folded over the tonguec of the plate c,

which is then slid forward, so as to bring the fold past the sewing-linea5 of the needle. The distance a4 from the point of the tongue c to thesewing-line ofthe needle determines the depth of the tuck. The cloth isfed past the needle in the direction of the arrow in Fig. 4. The part ofthe needle-plate just over the tongue c', where the plait is formed tomake the tuck, is cut away, as shown in Fig. 4.. A drag pin or peg d,passing through the cover-plate a3 and the needle-plate a2, puts aslight drag on the cloth and by keeping it taut on the tongue ccontributes to more perfect work and straighterfeeding at high speeds.The drag-pin d is set nearer to or`farther from the tongue c', accordingto the depth ot' the tuck to be formed. Several pegholes are provided toenable this adjustment to be lnade. The tuck is first formed over thepoint of the tongue c. When the tongue is slid forward in the positionshown in Fig. 4, the part of the fabric between d and the tongue will besubjected to'frictionol` drag, which will be greater or less, accordingas the pin dis nearer to or farther from lthe tongue.` The plate c ismounted in fixed guideways, in which it may be slid longitudinally bythe lever c2. One of the guide-bars c3 is graduated to enable the plateto be readily set for any depth of tuck. An important feature of theinvention is that the plate c and itsfixed carrying-guides are mountedin such a manner as to be detached from the sewing-machine proper-as,for example, on a separate.

ing appliance the cloth canhang or freely fall down under the table ofthe machine as the work proceeds both before and after the formation ofthe tuck. To prevent the cloth fouling the needle-bar or presser-footwhen an inverted machine is used, a shield-plate s is carried by a leverCZ', having its fulcrum at d2 under the table of the machine. Whensewing is proceeding, the shield occupies the position shown in Fig. 1.When it is desired to gain access to the needle-bar, the shield s isswung outward away from the needle-bar. After the rst tuck is formed thedistance apart of the succeeding tucks is determined by a gage or guidere. This consists of two thin plates of metal, which may be set atVarying distances apart by means of set-screws.

It is carried by a lever or arm e', carried by back to the left aboutits hingepin e2. The last tuck made is inserted between the plates ofthe guider e, as shown in Fig. 5, and as the Work is fed forward thistuck acts as an automatic guider or gage for insuring the parallelism ofthe tuck actually being made with the one previously made.llarkingz-lines or other devices of a like nature for a similar purposeare thus unnecessary. The distance of the guider e from the sewing-lineof the needle determines the pitch or distance apart of the tucks, andby sliding the plate e4 any desired pitch may be lobtained.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1, For forming tucks in textile fabrics the combination with asewing-machine of the adjustable cover-plate d3 the drag-pin d and thelongitudinally-adjustable tongue-plate c, the latter mounted in fixedguideways detached from the sewing-machine proper at its operative partso as to present no obstacle to the hang 0r fall of the fabric in frontof and to the rear of the sewing' mechanism substantially as set forthand shown.

2. For forming tucks in textile fabrics the combination With asewing-machine of the adjustable cover-plate a3 the dragpin CZ thelongitudinally-adjustable hinged guider or gage e and thelongitudinally-adjustable independently-supported t0ngue-plate c,substantially as set forth and shown.

3. For forming tucks in textile fabrics the combination with an invertedsewing-machine of the shield s the adjustable coverplate a3 the drag-pind the guider or gage e and the independently-supportedlongitudinally-adjustable tongue-plate c substantially as set forth andshown.

In testimony whereof I hereunto alix my signature in presence of twoWitnesses.
